One of the leaders of wall materials in the modern market, which combines high constructional and thermal insulation properties, is cellular concrete, in particular non-autoclave hardening. Improving efficiency of cellular concrete as a heat insulating material is, above all, in the maximum possible decrease in average density, while providing a certain level of physical and mechanical indicators necessary for the manufacture of products in the form of slabs.

One of the actual problems of the further sustainable development of construction industry is solution of energy and resource saving problems during production and reduction of harmful emissions. Building materials based on gypsum raw compared to cement materials of analogical purpose are characterized by low energy consumption, as well as better ecological indicators. However, gypsum materials without modifying additives have low strength and water resistance which limits their application to the area of internal processing of rooms with a relative humidity of up to 60 %.
